hey, I'm developing a custom stm32f405rgt6 board. I'm using stlink for uploading code. I'm comparitively new to stm as i've only worked with blue pill. I get "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a...
Context: I am trying to read the Chip ID from a BMP280 sensor using SPI communication with an STM32 microcontroller. The expected Chip ID value is 0x58. However, I am encountering inconsistent results when calling the function to read the Chip ID mul...
Hi there,I've been using the NXP Kinetis MKL03Z32VFK4 Ultra-Low Power Cortex-M0+ MCU in our products, and it's been working well, but due to a major redesign, I'm looking for alternatives, and ST MCUs are promising.Specifically, I'm concerned about l...
I just was wondering how you guys proceed to choose an external crystal, specifically what speed it should have...The clock management with its tons of PLLs and dividers seems to be able to scale up almost any source to a desired frequency.for the L4...
In pins that share more than one GPIO, how do you set the GPIO to connect to the physical pin?For instance, for pins PA12/PA10 and PA11/PA9 one can remap them using SYSCFG_CFGR1 register. But is unclear for the rest of the pins. For example, TSSOP20 ...
I have an application which requires me to send unidirectional high-speed parallel data on preferably 2 (or 4) from several synchronous sources to an STM32. I'm thinking of using the U575, but that's not set in stone.My requirements do not seem to fi...
I have design pcb for Stm32H723VGT6 ( 100 pins TQFP ) my job is read adc 12 bit and transfer over usb to PC . i have set sysclk to 550 MHz and ADC clock to 64 MHz so i got sample rate to 1.3 Msps but mcu are hot. So i have sysclk to 400 and ADC ...
I am working with STM32 U575/U5A5 and L4 series of STM32 controllers in low power mode. I have programmed the controller to wake for every 10s and blink LED. This issue what we observed is once immediately flashing hex file to controller using STlin...
Good morning,In regards to the current limit placed on the PC13-PC15 pins of the STM32G431VBx3 that is used as the basis of the STSPIN32G4 (and whose datasheet is referred to multiple times in the STSPIN's), the '431 datasheet has the usual low-power...
I have a system of sensors connected to an STM32 chip, all working via I2C and 3.3V.I've created interface libraries for my sensors, specifically the temperature and accelerometer ones. However, when I read the values measured by the sensors, I came ...
